    • The invention relates to a method for breaking ice with a motor-driven watercraft with three hulls, i.e. a trimaran (4), comprising a middle hull (3), a propulsion device (9), a right (1 ) and a left (2) side hull and a deck (5), where said three hulls are attached. In the method according to the invention ice is broken with the middle hull (3) of the trimaran. The invention also relates to a motor-driven watercraft with three hulls, i.e. a trimaran (4), comprising a middle hull (3), a propulsion device (9), a right (1) and a left (2) side hull and a deck (5), where said three hulls are attached. In the trimaran (4) according to the invention the propulsion device (9) is arranged in the middle hull (3) and a keel (7) in the longitudinal direction of the middle hull is arranged in the bow (3a) of the bottom of the middle hull for breaking ice. The invention also relates to the use of a trimaran (4) for breaking ice.
